First up is the Koldrak Fever event starting on July 22 and running through August 19. Note, however, that you’ll be able to redeem the rewards from July 22 through September 23. The event is available on Friday, Saturday, and Sunday where the Koldrak’s Lair daily quest should contain a bonus item for you. This item, called a Koldrak Cache, has a chance of containing several items from scales, embers, garnets, and more. If you nab enough Koldrak Embers, you can then turn them for rewards at the Dragon Express.
The Summer of Splendor event also runs from July 22 through August 19, with the reward redemption period running from July 22 through September 23. This event is all about using the rewards from this event to find the magical lamps such as Antique Lamps.
You’ll need to polish the lamps using Polishing Cloths in order to restore them. If you want to open them, do note they’ll have a five-hour cooldown when you do so,
“…the Lamps can be opened frequently each day for the duration of the event for various upgrade materials, including the event currency Wishing Charms and Scrubbing Charms. Wishing Charms and Scrubbing Charms can be spent in the Dragon Express for additional rewards of your choosing.”
